A Phase 3 Single-Arm Study of UGN-102 for Treatment of Low Grade Intermediate Risk Non-Muscle-Invasive Bladder Cancer (ENVISION)

A Phase 3 Single-Arm Study of UGN-102 for Treatment of Low Grade Intermediate Risk Non-Muscle-Invasive Bladder Cancer (ENVISION)

Brief Summary:
This Phase 3, multinational, single-arm, multicenter study will evaluate the efficacy and safety of UGN-102 as primary chemoablative therapy in patients with low grade intermediate risk non-muscle-invasive bladder cancer (LG IR NMIBC).

Detailed Description:
Eligible patients will receive 6 once-weekly intravesical instillations of UGN-102.

All patients will return to the clinic approximately 3 months after the first instillation for determination of response to treatment. Assessment of response will be based on visual observation (white light cystoscopy), histopathology of any remaining or new lesions by central pathology lab (if applicable), and interpretation of urine cytology by central pathology lab.

Patients confirmed to have a complete response (CR) at the 3-month Visit, defined as having no detectable disease (NDD) in the bladder, will enter the Follow-up Period of the study. Patients confirmed to have a non-complete response (NCR) will undergo Investigator designated standard of care (SOC) treatment of remaining lesions and then enter the Follow-up Period of the study.

During the Follow-up Period, patients will return to the clinic every 3 months for up to 24 months (ie, 27 months after the first instillation) for evaluation of response. Patients who remain disease free at the 27-month Visit will continue to return to the clinic every 6 months for up to 36 months (ie, 63 months after the first instillation) or until disease recurrence, disease progression, death, or the study is closed by the Sponsor, whichever occurs first.

Patients confirmed to have a disease recurrence during the Follow-up Period or a disease progression at the 3-month Visit or during the Follow-up Period will undergo Investigator designated SOC treatment and have a separate End of Study (EOS) Visit performed. The timing of the EOS Visit will be approximately 3 months after SOC treatment of disease recurrence or progression.
